Chris Oatley's podcast back catalogue recently and there was a episode which talked about the importance of bad drawings- how you shouldn't be put off by doing awful drawings because (oversimplification alert) you need them in order to improve. So here's one of my shitty drawings recently: eating lunch on the stairwell at work . I usually vet them before posting.
I highly recommend these podcasts . Chris talks about the practical aspects of working as an artist and has lots of nuts-and-bolts tips to improve.
